That makes only twelve names from Franklin to Whittier. Others could be included; but they are not so great as these. No one of these could be taken out of our literature without affecting it and, in some degree at least, changing the current of it. This is not to forget Bret Harte nor Samuel L. Clemens. But each is dependent for his survival on a taste for a certain kind of humor, not delicate like Irving's and Holmes's, but strong and sudden and a bit sharp. If we should forget the "Luck of Roaring Camp," "Truthful James," and the "Heathen Chinee," we would also forget Bret Harte. We are not apt to forget _Tom Sawyer_, nor perhaps _The Innocents Abroad_, but we are forgetting much else of Mark Twain. Whitman is not named. His claims are familiar, but in spite of his admirers he seems so charged with a sensuous egotism that he is not apt to be a formative influence in literary history. It is still interesting, however, to remember how frequently he reveals his reading of Scripture. Fortunately, all these writers are so near, and their work is so familiar, that details regarding them are not needed. Two or three general words can be said. In the first place, observe the high moral tone of all these first-grade writers, and, indeed, of the others who may be spoken of as in second rank. There is not a meretricious or humiliating book in the whole collection. There is not one book which has lived in American literature which has the tone of Fielding's _Tom Jones_. Whether it is that the Puritan strain continues in us or not, it is true that the American literary public has not taken happily to stories that would bring a blush in public reading. Professor Richardson, of Dartmouth, gives some clue to the reason of that. He says that "since 1870 or 1880 in America there has been a marked increase of strength of theistic and spiritual belief and argument among scientific men, students of philosophy, religious 'radicals,' and others." He adds that while much contemporary American literature and thought is outside the accepted orthodox lines, yet "it is not hostile to Christianity; to the principles of its Founder it is for the most part sincerely attached. On the other hand, materialism has scarcely any hold upon it." Then follows a very notable sentence which is sustained by the facts: "Not an American book of the first class has ever been written by an atheist or denier of immortality." That sentence need not offend an admirer of Walt Whitman, for he "accepts both theism and the doctrine of the future life." American thought has remained loyal to the great Trinity, God, Freedom, and Immortality. So it comes about that while there are a number of these writers who could be put under the ban of the strongly orthodox in religion, every one of them shows the effect of early training in religion and in the Scripture.[39]
